2-(3-Chloro-5,6-diphenyl-2,5-dihydro-1,2,4-triazin-5-yl)-2-methylpropanenitrile
The title compound, C(19)H(17)ClN(4), was obtained from the reaction of 3-chloro-5,6-diphenyl-1,2,4-triazine with isobutyronitrile in the presence of lithium diisopropyl-amide as an unexpected product of covalent addition of isobutyronitrile carbanion to the C-5 atom of the 1,2,4-triazine ring. The 2,5-dihydro-1,2,4-triazine ring is essentially planar (r.m.s. deviation = 0.0059 Å) and the 5- an...

The title compound, C21H16N4, obtained under standard Suzuki cross-coupling conditions, is a model compound in the synthesis and biological activity evaluation of new aza-analogues of sildenafil containing a pyrazolo-[4,3-e][1,2,4]triazine system. An N-H⋯N intra-molecular hydrogen bond involving the amino-benzene system and the 1,2,4-triazine moiety helps to establish a near coplanar orientatio...
متن کاملN-{2-[(4S)-4-tert-Butyl-4,5-dihydro-1,3-oxazol-2-yl]phenyl}-5,6-diphenyl-1,2,4-triazin-3-amine
The title compound, C(28)H(27)N(5)O, was synthesized using palladium cross-coupling amination of 3-bromo-5,6-diphenyl-1,2,4-triazine with 2-[(4S)-4-tert-butyl-4,5-dihydro-1,3-oxazol-2-yl]aniline. The oxazoline ring is almost planar, with a maximum atomic deviation of 0.023 (5) Å. The phenyl rings make dihedral angles of 29.0 (1) and 54.6 (1)° with the triazine ring while the benzene ring makes ...
متن کامل2-[3-Acetyl-5-(2-chloro-3-pyridyl)-2-methyl-2,3-dihydro-1,3,4-oxadiazol-2-yl]-4-fluorophenyl acetate
In the title compound, C(18)H(15)ClFN(3)O(4), the dihedral angle between the substituted pyridine ring and the oxadiazo-line ring is 9.73 (19)° and the acyl group is coplanar with the oxadiazo-line ring [O-C-N-C torsion angle = -2.1 (3)°]. Furthermore, the substituted benzene ring is almost orthogonal with the oxadiazo-line ring, the dihedral angle between them being 87.56 (18)°.
